convert mp3 to wav using xuggle getting exception

Question

I am trying to convert mp3 to wav and the code is here:

String mp3 = "F:\\work\\pic2talk38512.mp3";
String wav = "F:\\work\\pic2talk38512.wav";
TranscodeAudioAndVideo.transcodeTest(mp3, wav);

public static void transcode(String sourceUrl, String destinationUrl) {
    IMediaReader reader = ToolFactory.makeReader(sourceUrl);
    reader.addListener(ToolFactory.makeWriter(destinationUrl, reader));

    while (reader.readPacket() == null)
            do {
            } while (false);
}

I got this exception:

I know that xuggle can figure out the conversion by the extension.But why this time is failed?

thanks

edit:

previously I can convert mp3 which params(MPEG 22.1KHZ 32kbps) to wav, but If I use the mp3(MPEG 44.1KHZ 62kbps) I got this exception?

How this happened?

In this ,basically xuggle is complaining about your codec.I think you need to try this code

String mp3 = "F:\\work\\pic2talk38512.mp3";

String wav = "F:\\work\\pic2talk38512.wav";    
IMediaReader mediaReader = ToolFactory.makeReader(mp3);
            IMediaWriter mediaWriter = ToolFactory.makeWriter(wav, mediaReader);
            mediaReader.addListener(mediaWriter);
            // IMediaViewer mediaViewer = ToolFactory.makeViewer(true);
            // mediaReader.addListener(mediaViewer);
            while (mediaReader.readPacket() == null);

I hope you are using xuggle-xuggler-5.4.jar

Update:

import com.xuggle.mediatool.IMediaReader;
import com.xuggle.mediatool.IMediaViewer;
import com.xuggle.mediatool.IMediaWriter;
import com.xuggle.mediatool.ToolFactory;
public class TranscodingExample {
    private static final String inputFilename = "c:/myvideo.mp4";
    private static final String outputFilename = "c:/myvideo.flv";
    public static void main(String[] args) {// create a media reader
        IMediaReader mediaReader =
               ToolFactory.makeReader(inputFilename);
        // create a media writer
        IMediaWriter mediaWriter =
               ToolFactory.makeWriter(outputFilename, mediaReader);
        // add a writer to the reader, to create the output file
        mediaReader.addListener(mediaWriter);
        // create a media viewer with stats enabled
        IMediaViewer mediaViewer = ToolFactory.makeViewer(true);
        // add a viewer to the reader, to see the decoded media
        mediaReader.addListener(mediaViewer);
        // read and decode packets from the source file and
        // and dispatch decoded audio and video to the writer
        while (mediaReader.readPacket() == null) ;
    } 
}

This is the code taken from Java Code Geeks. Try changing the path to your mp3 files and see if that works for you

I have used Xuggler previously. Let me have a look. In the mean time, try changing the back slashes to forward slashes :) – An SO User Apr 11 '13 at 09:41
this is not the slashers issue.OP is using slashes correctly. – Freak Apr 11 '13 at 09:47
previously I can convert mp3 which params(MPEG 22.1KHZ 32kbps) to wav using demo code, but If I use the mp3(MPEG 44.1KHZ 62kbps) I got this exception. – Felix Apr 11 '13 at 09:52
I can convert mp3 which is downloaded from google voice to wav, but I can not convert my mp3 to wav.How this happened... – Felix Apr 11 '13 at 09:54

@LittleChild dont be so excited.It can happen because of the variations of codec.do concentrate what @felix is saying `I can convert mp3 which params(MPEG 22.1KHZ 32kbps) to wav using demo code, but If I use the mp3(MPEG 44.1KHZ 62kbps) I got this exception.` You need to read this comment again – Despicable Apr 11 '13 at 09:58

@LittleChild Can I send my mp3 to you by email? If you don`t want to public your email here, my email is guofuchunlh@gmail.com and would you send me an email and I send mp3 to you? thanks ): I think my mp3 file is wrong but I can play it... – Felix Apr 11 '13 at 10:24
